The Waning Moon

The Waning Moon (欠けていく月) is the eleventh episode of Iroduku: The World in Colors. It premiered on December 15, 2018.

Synopsis
Aoi walks her home after Hitomi bursts into tears. The next few days bring intense preparation for the Magic Photography Art Club, but while cleaning up Hitomi suddenly disappears only to reappear again, remarking as if time stopped for a moment and arousing Kohaku's worries. Kohaku mails Professor Uttley from her magic school at England, discovering that time magic is not permanent, and that because Hitomi's presence is an anomaly it will definitely cause divergences in the course of the past, creating inevitable "time gaps" where the person or object in question can stand to remain stuck there should it stay for too long. With her teenage self still lacking in magical power, Kohaku requests that Hitomi collaborate with her to send her back to her original time and desperately tries to find the purest high-quality starsand as possible, enlisting the help of everyone else in the club. Meanwhile, Hitomi struggles with her lack of motivation on returning home and starts disappearing more frequently. Kohaku decides that Hitomi will depart in two days on the night of the Cultural Festival, where a new moon will appear to maximize the powers of the starsand. That night, Hitomi sends a paper aeroplane to Aoi at night and they embrace each other after meeting up, confirming their feelings for each other.
